Energy management of DC powered home systems in Iraq
(İstanbul Gedik Üniversitesi, 2022) Daham, Mohammed Rashad; Ulutagay, Gözde
Solar energy is mostly important forms of renewable energy, although equipment for exploiting this energy is still very expensive. One of the most important challenges facing solar energy systems is the ignorance of societies about the culture of renewable energy and the ways to benefit from it. The large number of energy conversion processes from one form to another is considered one of the most important causes of energy loss due to the low efficiency of the conversion circuits and the losses that caused by the conversion processes because of the switching operations and thermal loss of the switches. An electrical energy management system has been proposed for a house that is fed by a solar cell array independently of the grid, this house was fed with direct current in order to reduce energy conversion losses. The proposed house suits the climate of Iraq, which is often hot and dusty in many cases. The presence of alternating current loads was taken into consideration, so a high efficiency voltage source converter was added to supply these loads. The results of the system simulation, which was conducted using the MATLAB/SIMULINK program, showed a good performance and high efficiency in the process of exploiting solar energy.
